I am not sure how to get ahold of the Whisnant's - Reid has passed away a number of years ago but his son Mark (ran P/S for a while) is still around. I am not sure how much help Mark would be as he would have only been a kid or possibly not even born when Reid had the 67 but he might be able to put you in touch with someone his Dad might have raced with at the time? They were in the Atlanta, GA area if I recall correctly - Plumbing business and also later Atlanta Race Cars.
